BNP stands for B-type Natriuretic Peptide.
What does BNP mean?
a blood marker used to help assess heart failure
BNP stands for B-type natriuretic peptide, a hormone released by the heart when its chambers are stretched or under strain, as happens in heart failure. A blood test measures the BNP level to help diagnose heart failure and judge its severity. A higher BNP suggests more cardiac strain, while a low level makes heart failure less likely. It is often used together with symptoms and imaging to guide diagnosis and treatment.
When is BNP used?
BNP is ordered in emergency, cardiology, and general medical settings, often when a patient presents with shortness of breath.
Frequently asked questions
What does BNP stand for?
BNP stands for B-type natriuretic peptide, a blood marker used to help assess heart failure.
What does a high BNP mean?
A higher BNP suggests more strain on the heart, which supports a diagnosis of heart failure.
Why is BNP tested?
It helps diagnose heart failure and judge its severity, especially in someone with shortness of breath.
Can a low BNP rule out heart failure?
A low BNP makes heart failure less likely, though results are always interpreted with symptoms and other tests.
